COMBINED COTTON SCRAPER AND CHOPPER.

SPECIFICATION forlning part f Letters Patent No. 450,480, dated April 14, 18919 Application filed September 3, 1890. Serial No. 364,311. (No model.)

T0 all whom, t may concern- JPEL, a citizen of the United States, and a resi-- dent of Lorado, in the county of Greene and State of Arkansas, have invented certain new and useful Improvements in a Combined OottonScraper and Chopper; and I do hereby declare that the following is a full, clear, and eX- act description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in combined cotton Scrapers and choppers, in which the sera-pers can be readily removed and plows be substituted therefor.

The object of the invention is to provide a device of the character described which shall b e cheap and economical in manufacture, simple in construction, and reliable and efficient in use.

The invention consists in the novel construction and combination of parts hereinafter fully described, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a combined cotton scraperand Y chopper constructed in accordance with my invention. Fig. 2 is a side elevation of the same,thenearwheelbeingremoved. Fig.'3is a detail view of one of the scrapers, showing the manner of applying or attaching it to the beam. Fig. 4 is a detail view of the segmental plate with which the drag-bars are connected.

I ngthe said drawings ,the reference-numeral l designates the axle of the apparatus, and 2 the wheels thereof.

3 denotes the tongue.

Mounted upon the axle l is a bevel gearwheel et, which meshes with a pinion 5 on the shaft 6, journaled in bearings 7 on the crossbars 8, which are connected with the horizontal pieces 9, pivoted to the axle. This shaft 6 also carries a sprocket-wheel 10, which is connected with a similar wheel 12, carried by the Shaft 13, journaled in the depending brackets 14. This shaft 13 is connected by universal joint with the chopper-shaft` 15, which projects rearwardly, and is provided at its end with a hub 1G, having arms 17, to

Which are secured the chopper-blades 18. The shafts 6 and 13 are also provided with differential sprocket-Wheels 10n and12 for varying the speed of the chopper-shaft.

The numeral 19 denotes a segmental arm i having a series of apertures 20. This arm is secured to the rear cross-bar S, and is connected by means of pin 21 with a link 22.

The numeral 22 denotes two drag-bars connected at their front end with bar23, having a hook 24, which engages with the link 22. At their rear these bars are curved downwardly and carry the Scrapers These Scrapers may be of any ordinary or suitable construction, and are provided with curved plates 26, which embrace the curved ends of the drag-bars 22a, and each is provided with a slot 27, through which passes the headed pin or bolt 28, by which the plates are secured to the Scrapers. The plates are also provided with central slots or apertures 29, which engage with headed pins 30, which pass through dragbars 22, and also through an angular supporting-plate 3l.

Secured to the drag-bars 22 are two downwardly-depending clips, which screw and hold in position a transverse plate 32, carrying a block 33, which in turn carries a bracket 34, Which forms a bearing for the rear end of the chopping-bar.

From the above it will be seen that the Scrapers can readily be removed and plows be substituted therefor when desired, and also that the arms and shaft carrying the Scrapers and chopper bar or shaft and connections can be removed from the axle and other devices be used instead.

Secured to the tongue is a rearwardly-projecting curved bar having at its free end two transverse hooked arms 35, which are adapted to engage with a loop 36, secured to arms 22, by which the Scrapers and choppers are supported in an elevated position.

Having thus described my invention, what I claim is 1. In a combined cotton scraper and chopper, the combination, with the wheels and axle and gearing connected therewith, of the rotating chopper-shaft connected by a universal joint to the geared shaft and supported from the arms or drag-bars carrying the IOC Scrapers orb1z1des,and the curved bar secured l the said slotted plates to the curved drag-bars, to the tongue having transverse hooked arms substantially as described. engaging with aloop secured tothe drag-bars, In testimony that I claim the foregoing as substantially as described. my own I have hereunto affixed my signature 5 2.
